Please **do not** post requests for help (e.g. with installing or using LAMMPS) here.
Instead send an e-mail to the lammps-users mailing list.
Instead, you can post to the LAMMPS category in the Materials Science Community
Discourse forum at: https://matsci.org/lammps/
This issue tracker is for tracking LAMMPS development related issues only.
Thanks for your cooperation.
Thank you in advance for your cooperation.

.. admonition:: Software version requirements for testing
:class: note
The compiler and library version requirements for the testing
framework are more strict than for the main part of LAMMPS. For
example the default GNU C++ and Fortran compilers of RHEL/CentOS 7.x
(version 4.8.x) are not sufficient. The CMake configuration will try
to detect compatible versions and either skip incompatible tests or
stop with an error.
After compilation is complete, the unit testing is started in the build
folder using the ``ctest`` command, which is part of the CMake software.
The output of this command will be looking something like this::

Pair styles
===========
Classes that compute pairwise interactions are derived from the Pair
class. In LAMMPS, pairwise calculation include many-body potentials
such as EAM or Tersoff where particles interact without a static bond
topology. New styles can be created to add new pair potentials to
LAMMPS.
Classes that compute pairwise non-bonded interactions are derived from
the Pair class. In LAMMPS, pairwise calculation include many-body
potentials such as EAM, Tersoff, or ReaxFF where particles interact
without an explicit bond topology but include interactions beyond
pairwise non-bonded contributions. New styles can be created to add
support for additional pair potentials to LAMMPS. When the
modifications are small, sometimes it is more effective to derive from
an existing pair style class. This latter approach is also used by
:doc:`Accelerator packages <Speed_packages>` where the accelerated style
names differ from their base classes by an appended suffix.
Pair_lj_cut.cpp is a simple example of a Pair class, though it
includes some optional methods to enable its use with rRESPA.
The file ``src/pair_lj_cut.cpp`` is an example of a Pair class with a
very simple potential function. It includes several optional methods to
enable its use with :doc:`run_style respa <run_style>` and :doc:`compute
group/group <compute_group_group>`.

Set attributes of the simulation box.
For triclinic (non-orthogonal) simulation boxes, the *tilt* keyword
allows simulation domains to be created with arbitrary tilt factors,
e.g. via the :doc:`create_box <create_box>` or
:doc:`read_data <read_data>` commands. Tilt factors determine how
skewed the triclinic box is; see the :doc:`Howto triclinic <Howto_triclinic>` page for a discussion of triclinic
boxes in LAMMPS.
LAMMPS normally requires that no tilt factor can skew the box more
than half the distance of the parallel box length, which is the first
dimension in the tilt factor (x for xz). If *tilt* is set to
*small*, which is the default, then an error will be
generated if a box is created which exceeds this limit. If *tilt*
is set to *large*, then no limit is enforced. You can create
a box with any tilt factors you wish.
Note that if a simulation box has a large tilt factor, LAMMPS will run
less efficiently, due to the large volume of communication needed to
acquire ghost atoms around a processor's irregular-shaped sub-domain.
For extreme values of tilt, LAMMPS may also lose atoms and generate an
error.
